A curved segment of an existing road has a radius of 180 m, which restricts the posted speed limit for that segment to 75% of the speed limit of the road. If this segment of the road is to be improved so that the posted speed limit is that of the rest of the road, determine the radius of the improved segment. The maximum superelevation allowed is 8%.
